Design and development

The Norwegian airline Widerøe decided in the late 1940s to design and build a general-purpose aircraft for its own use. Built in the airline workshops the Widerøe C.5 Polar was a braced high-wing monoplane which could be operated on floats, skis or wheels. It had an enclosed cabin for a pilot and up to five passengers, the passenger seats were removable to enable the aircraft to be used for freight or as an air ambulance. The first C.5 Polar was built and flown in 1948.

Operational history

A small number of aircraft entered service with the Widerøes Flyveselskap airline.
